Imagine you’re standing in line for the American Dream.You work hard, sometimes in dangerous jobs. You lead a moral life. But the line is stalling, even moving backwards. Yet you see newcomers up front — some of them immigrants and people of color.Maybe you’ve worked all your life alongside African Americans and Latinos — more than most northern liberals have — but when you complain about people cutting you, those liberals call you racist. Worse still, they seem to look down on you because of your Christianity, or your Southern culture.
